Data format
     Data are in grads format. Please use the information for each data to make the control file for grads. Sample fortran code for reading the data is shown below.

      parameter (ixyz=201, jxyz=201, kxyz=40)
      real      dbz(ixyz, jxyz, kxyz)

      open (unit=21, file=file_in, form='unformatted',
     &      access='direct',recl=ixyz*4)
      irec=0
      do k=1,kxyz
         do j=1,jxyz
            irec=1+irec
            write (21,rec=irec) (dbz(i,j,k),i=1,ixyz)
         enddo
      enddo


Remarks.
1) Data are stored in the cartesian coordinate (x, y, z).
   Data intervals are 1km, 1km, and 0.5km, respectively.
2) (x, y) starts from 100km west and 100km south from the radar,
   whose position is shown in mirai***_information.txt file.
3) z ranges from 0.5km to 20km.
